PAPER-BAG MACHINE.

I Specification forming part of Letters Patent No. 38,253, dated April 21, 1863.

To aZZ whom it may concern:

Be it known that I, JOSEPH WELLS, of Hoboken, in the county of Hudson and State of New Jersey, have invented a new and useful I Machine for the Manufacture of Paper Bags for the Use of Grocers and Others; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, in which- Figure 1 is a sectional top view. Fig. 2 is a sectional side view. Fig. 3 is a perspective view. Fig. 4 is a detached view of lap-folder 1, and Fig. 5 is a detached view of the severing-knife E.

The construction of my machine is substantially as follows: Iprovide aframe of suitable size and form to contain the machinery. In one end of this frame there are placed the rollers Q R S, with their middle placed at a distance from the center line of the machine equal to one-half of the required width of the lap and on the side of said line on which is situated the lap-folder H. The roller R is made in an elliptical form.

Situated a convenient distance forward of the rollers Q R S, and set up edgewise, are two guide-blocks, F G, with the center line of the machine passing between them. They are of suitable length and of any convenient width exceeding the required width of the folded 1 aper, and from their outward lower ends they are beveled to an angle of forty-five degrees (more or less) nearly to their upper edge, the remaining distance being slightly rounded up. The inside angle of the ends of said guideblocks are rounded off, and the distance between their respective planes is such that the thin adjustable gage-wheel K will move freely between them, with a thickness of paper on each sideof it. Said wheel is of any required diameter, and is situated near the outward ends of said guide blocks, with its lower edge adjusted a distance from the upper edge of said guide-blocks equal to the required width of the folded paper. On the upper edge and near the outward end of the guide-block F is fixed one of the lap-folders, H, which is made in the form of a right-angled triangle, with its short line extending directly across the edges of said guide-blocks, thus situating its hypotenuse obliquely across the said edges. Between the plane of said lap-folder and the edge of the guide-block G there is sufficient space to allow the lap to pass through. The other lap-folder, I, is situated behind the lapfolder H and on the guide-blockF with it, and is constructed substantially the same; but instead of its plane being at right angles with the plane of the guide-block F it is parallel with and at a distance from it sufficient to allow the folded lap to pass through. A portion of the guide-block G is removed to allow the lap-folder I and the paste-wheels W X to be placed in their proper position. One of said paste-wheels, W, is placed in a horizontal position, with its edge rolling against the edge'of the folded paper which the lap is to be folded on and between said lap-folders. The other paste-wheel, X, revolves in the paste-box c, with the upper edge of its inside plane work ing against the edge of the paste-wheel W. Directly forward of said guide-blocks there are situated two upright feed-rollers, B B, of a circumference corresponding with the required length of the bag and the lap forming its bottom, and of any convenient length exceeding the width of the folded paper. There is fixed in one of these feeding-rollers, B, a severing knife, E, with an indented edge, which extends from the upper end of said roller down nearly to its middle, when it turns in a forward direction in respect to the motion of said roller and extends obliquely across said middle the required distance, when it turns again and extends down to the lower end of the roller. The two straight edges of said knife are set aside one from the other a distance corresponding with the width of the lap required for forming the bottom of the bag, and in its middle there is formed a slot, T, of suffioient width and depth to clear a securing rod, J. Said securing-rod passes between said feeding-rollers in the grooves V V, formed in their middle circumference. The feeding-roller B has a groove, U, to receive the edge of the severing-knife E. The securing-rod J passes between the guide-blocks F G, and is attached to the support 7310f the adjustable gage-wheel K. The other end, just after passing between the feedingrollers B B, terminates in the angle of a changingplate, 0, said chan gin g-plate is of any required length, and the greatest width of its angle is slightly less than the width ofthe folded paper,

the thickness being such as is required. It is angular in its form, and has a portion of its end or angle removed, thus leaving a bearing on either side, which rests upon one of the drawing-rollers, D. When in its proper position, a transverse line of its plane will be at right angles with the feeding-rollers B B.

Situated above the drawing-roller D, and working against it, is another drawing-roller, L. The diameters of said drawing-rollers are r duced where the bearings of the changingplate 0 pass between them sufficient to prevent their acting upon said bearings. Said drawing-rollers are operated by the pulley 7c and belt f.

At a convenient distance from the drawingroller D, and on a horizontal line with it, are placed two folding-rollers, M N, working together, and are operated by a belt, g.

Situated above the folding-rollers M N is a paste-box, P, the bottom of which terminates in a slot, Z, of any convenient length exceeding the width of the folded paper. Working against said slot Z is a pasting-plate, 0, its length sufficient to cover said slot, and its width such that during its operation said slot is always closed. Said pasting-plate is attached by arms to a paster-shaft, h, and is operated by the levers b e, connecting-rod Y, and the cam an, attached to one end of the drivingshaft 1. When not operated upon, said pasting-plate is held with its lower edge nearly up to the lower edge of the paste-slot Z by the spring 01, and is so arranged that in its downward movement said lower edge of pastingplate 0 passes between the folding-rollersM N.

The feeding-rollers B B are operated by miter-wheels m m m m, attached to the lower end of their respective shafts and to the shaft 1, which is provided with a crank, A.

The operation of the machine thus constructed is as follows: The paste-boxes e P are supplied with paste, and a roll of paper of the required width is placed on the roller Q. The end of the paper forming the said roll is now passed over the roller S and under the roller it, which, being elliptical in its form, preserves the bearing across the paper while it is being folded. The end of the paper is now passed under the adjustable gage-wheel K, which holds it down the required distance from the upper edge of the guide-blocks F G, while its two sides are being folded by said guide-blocks, as they pass between them.

The middle of the roll of paper having been placed one side of the center line of the machine, one of its edges will now be even with the upper edge of the guide-block G, while its other edge will project above the upper edge of the guide-block F a distance sufficient for forming the lap, which, coming in contact with the lap'folder H, is folded by it across the edge of the guide-block G. The other edge now passes between the guide-block F and the edge of the paste-wheel W, causing it and the pastewheel X to revolve, and thus applies the paste. The operation of foldingthe lap is completed as the folded paper passes along to the feeding'rollers B B, by the lapfolder 1. If, now, the feeding-rollers B B are put in motion by turning the crank A in the direction indicated by'the arrow, the folded paper will be drawn between them, and the above-described operation of folding and pasting will be continued till the roll of paper has all passed through the machine. At each revolution of said feeding-rollers the severing-knife E cuts off the folded paper, with the exception of the space left on either side by the slot T in its edge. The lower half of the folded paper, as cut by said severing-knife,

will extend beyond the upper jhalf sufficient.

to form the bottom lap of the bag. It now passes on to the changing-plate O, by which its center lines are changed to its edges, and vice versa, thus bringing the bottom lap into its proper position to be folded when it passes over the folding-rollers M N. It now passes between the drawing-rollers D L, being drawn forward by them, (the said uncut spaces serving to hold it together,) between the feedingrollersB B and said drawing-rollers. Itpasses the required distance beyond the vertical line of contact of the folding-rollers M N, when the cama operates thepasting-plateO, causing its lower edge to descend upon it, forcing it between the said folding-rollers, at the same time causing the lap forming the bottom of the bag to come in contact with its surface of paste, when said cam ceases its action, and it is raised to its upper position by the spring 01. The lap is now rolled onto the bag by the action of said folding-rollers. The said folding-rollers are operated by the belt g, and move more rapidly than said drawing-rollers, thereby creating a tension, which severs the said uncut spaces between them. The tension of the belt 9 is so regulated that it slips when one bag is being acted upon at the same time by both sets of rollers D L and M N.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. The guide-blocks F G, constructed and arranged in respect to each other substantially as and for the purpose set forth.

2. In combination with the said guideblocks, the adjustable gagewheel K, or its equivalent, as set f0rth,for the purpose specifled.

3. The arrangement of the lap-folders H I in respect to each other, and in combination with the said guide-blocks, substantially as and for the purpose specified.

4. The changing-plate G, with its securingrod J, or their equivalent, arranged and operating as set forth, for the purpose specified.

5. The peculiar combination of the said changing plate and securing-rod with the said severing-knife and feeding rollers,.substantially as set forth.

6. The combination of the pasting-plate O, or its equivalent, with the paste-slot Z, substantially as set forth, for the purpose specified.

7. The combination of the said adjustable gage-Wheel with the elliptical roller R, as set forth, for the purpose specified.
